Hi,
Confirmed, this is a bug in the 6.2 management client, not in the server or your setup. Since 6.2.0 the Auto-link action sends an empty node list to the server, so it reports success and creates nothing. Layer 2 maps are not affected because their links are built by the server from topology data. Fix is tracked in https://github.com/netxms/netxms/issues/3681 and will be in the next 6.2 release.
Until then, "Link objects" still works, but it links two objects at a time and doesn't bind the link to interfaces.
